A homeowner booked a roof inspection on Tuesday. On Thursday she got an email asking whether she was still thinking it over. That is a drip campaign doing what it was set up to do and forgetting to notice that the person had already said yes.
A drip campaign is a short series of emails (sometimes texts) that you write once and that go out on a schedule to everyone who triggers it, such as a new subscriber, a quote request or a first purchase. The "drip" is the steady, spaced delivery. The risk is the same thing: the schedule keeps running whether or not the person has answered.
A four-step drip for quote requests
Redfern Roofing is a six-person company in Omaha. About 25 people a month fill in the quote form. Here is the drip they send to anyone who does.
- Minutes after the form: "Thanks, Dana. We got your request and Lucas will call you today between 2 and 5. Until then, here is what he will ask so you can have it ready: roof age, any leaks, and whether you have a recent insurance claim."
- Day 2: "Quick tip while you compare quotes: ask every roofer whether the price includes removing the old layer and replacing the underlayment. It is the most common difference between two quotes that look the same."
- Day 5: "Here is a short list of what a good inspection report should include: photos of each slope, the roof's age and a written price. If a quote has none of that, ask for it."
- Day 10: "Still deciding? No pressure. If you want a second look at the quote, reply to this email or call the office at the number below, and we will walk through it."
Each message says something different, and none of them repeats the pitch. That is what separates a drip that gets read from one that gets filed under junk.
Where a drip and a follow-up sequence part ways
People use the two words as if they were the same. They are not, and the difference is what happened to the woman with the Thursday email.
| Drip campaign | Stop-on-reply sequence | |
|---|---|---|
| Starts when | Someone opts in or takes an action | You decide to write to a named person |
| Message | Same for everyone in the group | Written or adjusted for that person |
| Stops when | The last email is sent, unless you add exit rules | They reply, in any way |
| Reads like | A newsletter or guide | A person checking in |
| Best for | Onboarding, reminders, education | Reaching people you picked |
If you are one person emailing people you chose, the right tool is the stop-on-reply sequence. Wording for that is in a cold email follow-up sequence that does not nag, and a sales follow-up sequence for service businesses shows it for quotes. A drip fits people who asked to hear from you and who all need the same information.
The arithmetic of a drip with no exit rule
Back to Redfern. Out of 25 quote requests, say 6 reply or book by day 3. Without an exit rule, those 6 still receive emails 3 and 4, which is 12 messages saying "still deciding?" to people who have decided. With the rule "stop when they reply or book", the 12 never go out. The 19 who stay in the drip get all four emails, which is 76 messages, plus the 6 who got only two, for 88 sent instead of 100. The saved 12 emails are the ones most likely to annoy.
Where a drip backfires
Three cases do the damage. Sending a drip to people who never asked for it, such as a purchased list, which costs you spam complaints and your sending reputation. Running the same cadence for a hot lead and a cold one. And never checking the series after you write it: a link that has since broken, or an offer that expired, goes out to every new person for months.
The law side is simple. In the US, CAN-SPAM expects an accurate From line, a physical postal address and a working unsubscribe in every message of the series. Honor an unsubscribe quickly. This is general information, not legal advice.
Keeping a drip personal at small volume
At 25 people a month you can afford to have step 1 come from a named person, include one detail from the form, and sign off with a real name that replies go to. Send from your own address, not a no-reply. At that size a human can read every reply, and a reply is worth more than a click. Leads that go quiet after the last email belong in the slower routine in how to reactivate old leads, and the idea of keeping someone warm over months is covered in what lead nurturing is.
Neighboring terms
An autoresponder is a single automatic reply. A nurture sequence is a drip aimed at leads that are not ready. A cadence is the timing pattern of any series. A trigger is the event that starts it. For outreach where every reply is read by something that can answer it, see outbound that reads the reply. If you also need the pipeline view, what a lead source is shows how to record where each lead came from.
Writing the series once is easy. Keeping it from emailing someone who already replied is the hard part. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own, and its AI worker stops when a person replies. Plans that get you customers start at $24.99 a month (Launch), and both Launch and Frontier start with a 7-day free trial, card required.
